TCAM profiles

TCAM profiles enable you to optimize TCAM resources according to your system requirements.

Note

TCAM profiles other than default are supported only on Extreme 8820, SLX 9740, SLX 9640, and SLX 9540.

TCAM is used by various forwarding applications. A TCAM profile supports a specified group of forwarding applications.

The following TCAM profiles are supported:

default: Optimizes resources with basic support for all applications. MCT is supported.
app-telemetry: Optimizes resources for application telemetry. MCT is supported.
border-routing: Optimizes resources for border routing and BGP Flowspec features.
cam-share: Enables TCAM sharing for security or policy-based routing (PBR) ACLs applied to multiple interfaces.
layer2-ratelimit: Optimizes resources for Layer 2 ACL egress rate-limiting and related applications.
(Not currently supported) multicast-profile: Optimizes resources for L2/3 IPv6 multicast.
vxlan-visibility: Optimizes resources for VXLAN transit visibility and GRE.

TCAM Profile Scaling (on SLX 9540, SLX 9640, SLX 9740, and Extreme 8820)

For Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices, the following table displays maximum TCAM entries by features and TCAM profile.

* For shared limits, the TCAM is filled using first-come first-served.

** DB is shared with L2 and L3 control protocol features.

NS = not supported.

RL = rate limiting.

BD = bridge domain.

TCAM Profile Scaling (SLX 9150, SLX 9250, Extreme 8520, and Extreme 8720 devices)

For Extreme 8720, Extreme 8520, SLX 9250, and SLX 9150 devices, the following table displays maximum TCAM entries by features. The only TCAM profile supported is default.

* For shared limits, the TCAM is filled using first-come first-served.

** DB is shared with L2 ctrl protocol, L3 protocol, and so forth.

NS = not supported.

RL = rate limiting.

BD = bridge domain.
